Sub-Q test injections, anyone actually switched over long term?

Been pinning IM for 6 years. Read some stuff on sub-Q for TRT showing steadier serum levels. Switched to sub-Q belly shots 0.5ml EOD about 2 months ago. Honestly the levels feel smoother - less of that post-pin spike. Anyone else made the permanent switch? Also wondering if blast doses actually work sub-Q or if you need to go back to IM once you push past TRT dosing.

I switched to sub-Q for TRT about a year ago and have not gone back. Using test cyp 0.35ml every 3 days. Levels are noticeably more stable than when I was doing 0.5ml twice weekly IM. Only issue early on was occasional nodules from using too large a needle - switched to 25g and that fixed it.

How does it work with thicker carrier oils? Some of the test e I have is in grapeseed which I imagine is harder to push through a small gauge needle sub-Q. Does the viscosity cause problems?
